Quick Answers

So, is Core i7-3555LE better than Core 2 Duo E8700?

It depends on what you want from the system. For gaming, Core 2 Duo E8700 is ahead with a 2.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i7-3555LE pulls ahead with 1.2% better PassMark.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core i7-3555LE is the stronger fit. You are getting 1.2% better PassMark, backed by 2 cores and 4 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Core i7-3555LE is still the much better call for a fresh build. Core i7-3555LE comes in 17.2% more expensive on MSRP at $300 MSRP versus $256 MSRP, and it still gives you 1.2% better PassMark. Core 2 Duo E8700 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 15.8% better value on paper (8.6 vs 7.5 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.

Which one is more future-proof for 2026 and beyond?

Core i7-3555LE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2009) and more multi-core headroom with 2 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
